IMPROVED CARPET-CLEANING- MACHINE.

The Schedule referred to in these Letters Patent and making part of thesame.

Nature and Object of the Invention.

My invention relates to machines made use of for cleaning carpets; and g7 Its nature consists in certain modifications in the details of thesame, and in the combination and ar-- lnngement of the parts thereof,hereinafter described and shown.

The accompanying drawing represents a vertical longitudinal section ofthe machine.

General Description.

The rollers aa, held in close contact with each other by means'of thelever b and weight a, revolve in opposite directions, as shown by thearrows, and thereby give motion to the endless co'rds d, which passbetween them and similar rollers, e e and f f; and over carrying rollersg h i.

'l'he hearings or journals of tberoller g are made adjustable, so that,by its being moved to the left, the cords may be tightened. I

The carpet, or other fabric, k, represented in the drawing by the redline, enters the-machine at], passes between the rollers at e 6, overthe roller h, between the rollers ff and a a, whence it falls on thefloor, or other receptacle.

After passing the rollers e e and h, the fabric is subjected to abcatingprocess, by means of the heaters m m, oscillating on the shafts mm, their oscillation being produced in one direction by the cams'n n,and in the other by either coiled springs 0 or coiled springs p; thefabric being held steady during the process by the rollers.

After the beating, the fabric passes between the rollers f f, and isfreed of most of the dirt and dust by the revolving cylindrical brush7', aided by a blast fronrthe pipe s. This pipe is closed at the ends,but is provided with an opening or openings, running the entire lengthof the pipe,in such a manner that the blast will be directed between thefabric and the brush.

The pipe 8 is connected, by a branch or branches, 3', with a fan orblower, t, which produces the blast. The

latter may consist of steam, superheated, and mixed I with air, or itmay consist of cold or hot air alone, the latter being usually employed,for the purpose of destroying moths and other insects.

The fabric passes now between two cylindrical re volving brooms, u u,and thence, after receiving a final brushing between the softer andshorterbrushes '1: 1 between the rollers a a, and out of the machine.

That part of the machinery which performs the cleaning-operation isenclosed, as far as practicable,

by a nearly air-tight case, w, terminating at the top in a pyramid andflue, x.

The latter is provided with a damper, y, to regulate the escape of theheated blast, to some extent.

. A spring may be used in lieu of the wcight'c.

' Claims. I do not claim, as my invention, any-of the parts, abstractly;but

\Vhat I claim, is.

1. The arrangement of the lcversjlg, weights 0, rollers a a, i, g, 0,It, and f f, endless cords d, cams n n, and heaters in m, as'hereindescribed and shown.

2. The combination and arrangement of the brush 7', fan t, branch-pipess and s, broom u u, and brushes 4; 'u, asherein described and'shown.
